This is a 12.4 mile out and back hike to Ostrander Lake with about 1617 ft. of elevation gain, from 7000 ft to over 8600 ft.
The trail head is located off Glacier Point rd. The first 3 miles of the hike are relatively flat. After 3 miles, the next 3 miles climbed at about a 10% grade. The mountain crests at about 5 3/4 mi then drops down to Ostrander Lake (8505 ft).
The trail is very rocky in spots so wear good hiking shoes. At this elevation, know your limitations. Bring plenty of water.
Be careful of the elevation, the air gets thin.
You can hike another 1,000 up the granite peak starting from the main campsite near the ski hut. We didn't do it, but a nearby group of hikers did and said the view was amazing (you can see the valley including half dome; etc). I tried fishing in Ostrander Lake but I am not as familiar with fishing for lake trout. The lake is full of jumping trout. A fly fisherman would have better luck I assume. Visited on Aug 05, 2013
